| 摘 要： | 以烤烟品种龙江911为试材,研究了当地常规施肥条件下重茬烤烟根茎叶干物质积累及产值变化规律.结果表明:重茬烤烟根茎叶干物质积累量随生育期延后呈现出逐渐增加的变化趋势,于17周达到最高值,随着重茬年数的增加干物质积累量呈现出降低的变化趋势,3个重茬处理之间均存在显著差异;重茬栽培对下部叶干物质积累影响最小,上部叶最大;重... |

| Abstract: | The dry matter accumulation of root,stem and leaves and variation rules of production value of flue-cured tobacco variety Longjiang 911 were studied in the fields with different continuous cropping years under conventional fertilization.The results showed that the dry matter accumulation of root,stem and leaves increased with the process of growth and development,and reached the highest in the 17th week.But the dry matter accumulation decreased with the increase of continuous cropping years,and there were significant differences between the three continuous cropping treatments.Continuous cropping had the least effects on dry matter accumulation of lower leaves,while the largest on that of upper leaves.Continuous cropping could significantly decrease the production value of tobacco,which was more obvious with the increase of continuous cropping years.Comprehensive analysis results indicated that continuous cropping should not exceed five years. |
